Abstract
A housing attachment for an electric machine is constructed in compliance with protection class IP 23 and includes a first projected edge disposed at a first border wall such that water located in the middle section at the first border wall drips off no later than at the first projected edge and is led directly or indirectly to the first air inlet opening. Proximate to the first air inlet opening are first laminates which deflect incoming air flowing into the feed air channel to a second edge area. Proximate to the second air outlet opening are second laminates that impart to the flow direction of the outgoing air leaving the outlet air channel a component directed to the top of the electric machine. Third laminates are disposed in an end area of the outlet air channel to deflect the outlet air flowing in the outlet air channel away from the top of the electric machine.
